WOVEN FABRIC.

Specification of Letters Patent.

Patented March.16, 1909.

Application filed January 20, 1908. Serial No. 451L621.

To all whom it may concern:

Be it known that I, WILLIAM B. lJANGE, a citizen of the Unlted States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Woven Fabric, of which the following is a specification.

Objects of the present invention are to provide a fabric adapted for use as a rug and for other purposes and having four solid color effects as distinguished from shot-about effects, that is having wefts of four colors and the wefts of each color always bound at back and face by warps of the same color.

The invention will be claimed at the end hereof, but will be first described in connection with the accompanying drawings, which are a diagrammatic view illustrating asection of a fabric taken in the direction of the warps and embodying features of the invention.

In the drawings the wefts are arranged in four weft planes, a face weft plane, a back weft plane and two middle or intermediate weft planes. The weft threads are of four different colors as is diagrammatically illustrated in the drawings. There are four warps each divided so that there are eight warps in all. The warps 1 and 2, correspond in color with the wefts 3; the warps 4 and 5, correspond in color with the wefts 6; the warps 7 and 8 correspond in color with the wefts 9, and the warps 10 and 11, correspond in color with the wefts 12. The fabric is a four ply fabric in the sense that its wefts occupy four Weft planes. On its face and on its back there are four color effects, made by rela tively interchanging the position of the plies, as is Well understood. Each color effect on the back and the face is unmottled and of solid color or hue. The face and back plies a,

and l), consist of plain tabby cloth, that is to say, the warps and the wefts are arranged in relation to each other as they are in plain In each of these tabby cloths warps of a given color both overlie and underlie wefts of the same color, thereby making solid uninottled color effects.

As shown in the drawing, the two intermediate plies c, consist of a double tabby cloth, that is to say, the warps are arranged as in plain weaving, but there are two wefts in each shed. There is therefore on the face and on the back a comparatively thin cloth making in all two thin cloths and there is in the middle a comparatively thick cloth so that there are three cloths in all.

The described fabric can be made bymeans of a full Jacquard loom and journal lifts are not required.

The back and face of the fabric present the same figure but in different colors, so that the fabric is reversible.

What I claim is:

A four ply fabric having on its back and face four color effects, each effect being of unmottled solid color and consisting of back and face plies of plain tabby cloth in each of which warps of a given color overlie and underlie wefts of the same color thereby making solid unmottled color effects, and the intermediate plies constituting a tabby cloth having two wefts in each shed, the plies being reversed throughout the fabric, substantially as described.

I11 testimony whereof I have hereunto signed my name.
